I think it's the species... I had a russian dwarf before and he was anything but shy, he'd beg for my attention... Victini only comes out for water and food.. but at least she doesn't bite! My old hammy would nibble.

Awwww soo cute. I used to have many hampsters over time. Only once have I had a dwarf and it was evil (litrally). It lived in a little house and only came out to eat or be agressive. My mum once put a tissue in and the thing came up and ripped the tissue while making noices like a steryotypical dog would with a chew toy. We could never hold it as it has bitten us soo many times before.
